Authentication device and system and method using same for on-line identity authentication and transaction

Abstract

The invention discloses an authentication device comprising an interface circuit, an indicator light, a visual screen and a safe chip, wherein the safe chip comprises a digital certificate, a private key, an encryption / decryption module and a digital signature module. The system which uses the authentication device for on-line identity authentication and transaction comprises an authentication device, a networking computer and an authentication / transaction computer. The method which uses the authentication device for on-line identity authentication and transaction has the key point that the authentication device decrypts encrypted information sent by an authentication / transaction server and carries out digital signature, and the authentication / transaction server verifies decryption information fed back by the authentication device. The invention improves the safety of on-line identity authentication and transaction by the visual screen, the encryption / decryption module and the digital signature module which are arranged in the authentication device and by the interactive cooperation of users and the authentication / transaction server, can effectively avoid the problems of Internet banking transaction hijacking, transaction falsification and remote control to embezzle user funds.
